RemoteFXvGPUDisablement Abuse Via AtomicTestHarnesses

Detects calls to the AtomicTestHarnesses "Invoke-ATHRemoteFXvGPUDisablementCommand" which is designed to abuse the "RemoteFXvGPUDisablement.exe" binary to run custom PowerShell code via module load-order hijacking. This technique leverages a signed binary to proxy execution of malicious code, specifically by exploiting module load-order hijacking to execute PowerShell commands.
